When a document ismore than five years old, and has not been reaffirmed, it is reasonable to conclude that its contents, although still ofsome value, do not wholly reflect the present state of the art.

Suggestions for changes in documents should be in the form of a proposed change of text, together withappropriate supporting comments.Interpretations: Occasionally questi

9、ons may arise regarding the meaning of portions of standards as they relate tospecific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiateaction to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned

10、interests, it isimportant to ensure that any interpretation has also received the concurrence of a balance of interests. For this reasonIEEE and the members of its technical committees are not able to provide an instant response to interpretation requestsexcept in those cases where the matter has pr

28、lar instrumentation and interface system of ANSI/IEEE Std583-1982, Modular Instrumentation and Digital Interface System (CAMAC) (also Report EUR 4100e of theCommission of the European Communities). The report on which this standard was originally based, ERDA ReportTID-26619, was prepared by the NIM

29、Committee* of the United States Energy Research and DevelopmentAdministration (now the Department of Energy) and the ESONE Committee* of European Laboratories. Thecorresponding ESONE document was ESONE/RTB/02.This standard differs from these original documents in several respects, particularly to be

30、 consistent with the newstandard for BASIC3that has been developed jointly by ANSI X3J2, ECMA TC21 and EWICS TC2. Enhancementsto the BASIC3standard include a real-time module that provides input-output to process peripherals, response toasynchronous events, synchronization and communication between

31、concurrent activities, and the handling ofexceptions.The BASIC3standard is general, and specific parts of the syntax and semantics are left open to be definedappropriately for particular process peripheral systems. The purpose of this standard is to define specific syntax andsemantics for use with C

32、AMAC in the areas left open in the standard.The revision of this standard was in conjunction with the 1981 review (1982 issue) of the entire family of IEEECAMAC standards undertaken to incorporate existing addenda and corrections into the standards.This standard was reviewed and balloted by the Nucl

48、ASIC for CAMAC1. IntroductionReal-Time BASIC for CAMAC is ANSI standard Real-Time BASIC in which the declarations and real-timestatements are defined for use with CAMAC hardware. The ANSI standard1defines process declarations andprocess input-output in a general way, independently of any particular

49、interface hardware. Specific parts of thesyntax and semantics of the language are left implementation defined so that an implementation for a particularhardware system can define these areas in the most appropriate way. The purpose of this standard is to provide astandard for reference, to achieve maximum compatibility between different implementations of ANSI BASIC for usewith CAMAC.The language is defined by formal syntax definitions and symbols. An explanation of these definitions and symbols isgiven in Annex A.It is
